Quick panel voltage vs. MPPT question

[Alan Ambrose]

Should the max MPPT voltage be compared against the panel's open-circuit or max power voltage?

 

For the panels I'm looking at (JAM54D41-445/LB) the max power voltage at 32.65V is only 83% of the open-circuit voltage of 39.1V. I'm pushing the max MPPT voltage with the number of panels I'm thinking of, hence the question.

You should use max. “Potential” voltage or open circuit voltage

OK ta.
